As with most nations, the USA Rank 1 Air lineup is decent. Expect slightly better armament and speed and slightly worse turning than average, but otherwise, there's no real surprises here.
Boeing P26 Peashoote A-33, A-34, A-34 M2, B-35
All of the P26 variants are quite similar - Mediocre speed, excellent turning ability (better than the stat card would imply), decent climb rate, but mediocre armament. For 1.0, they are quite adequate, but nearly useless beyond 2.0, which is standard for this tier of aircraft. Good for what they are, but use them only if you have nothing better.
There is a premium variant available, P-26A-34, if you REALLY want a premium version of a reserve vehicle for some reason.
Curtiss P36 Hawk A and C, aka Hawk 75L
Quick, fairly nimble, but still poorly-armed. The C variant is largely the same as the A, but has slightly better armament and the controls are slightly less stiff IMO. Both are above average for their BR, if not by much.

Curtiss BF2C1 Goshawk, aka Hawk III
Quite average for a reserve biplane. Slightly faster than the P26, VERY nimble, with decent climb rate, but the same mediocre armament. As with nearly all other reserve aircraft, it will serve you reasonably well below 2.0, but I wouldn't use the aircraft at any higher BR.
Grumman F3F-2
Slightly faster, slightly more nimble, and slightly better armed than the Goshawk. Better in every way! But only marginally so.
There is also a premium version, Galer's F3F-2.
Brewster F2A-1 Buffalo
Comparable with the P36C, but with better armament (3x.50 and 1x.30, instead of 1x.50 and 3x.30) and slightly worse turn times. Be a little more wary about getting into a turn fight, but otherwise you'll hold your own just fine.
There is also a premium version, John Thatch's F2A-1 Buffalo.
Vought OS2U Kingfisher -1 and -3
The two variants are basically identical, beyond the -3 having a significantly better climb rate than the -1. In either case, the vehicle is slow, relatively sluggish, and very poorly armed. Don't expect it to be useful outside of bombing light AI ground/naval targets and capping naval points.
Vought SB2U Vindicator -2 and -3, aka Chesapeake
The two variants are identical apart from the -3 having 4x.50 offensive and 1x.50 defensive, as opposed to the -2's 2x.30 offensive and 1x.30 defensive. For its intended role of dropping small bombs on small targets, both are effective, although the latter version has absolutely earned its 0.7 BR increase over the former. Neither perform extraordinarily well at their tier, but they do the job well.
Grumman TBF-1C Avenger
Our first level bomber! Not terribly fast, nor does it turn or climb well, but it does have TWO defensive MGs and, more importantly, it can carry 2000 pounds of bombs. Quite adequate for it's 1.7 BR.
Douglass SBD-3 Dauntless
Slow But Deadly. Well, it's slightly faster than the Avenger, and it has a noticeably better climb rate, but the maximum bomb load is cut in half. However, it is a DIVE BOMBER!!!!! which I find to be much easier to use when attacking individual targets, although it does prevent bombing from altitude. Two offensive .50s and two defensive .30s round out this little treat well. My personal choice for the 1.0-2.3 range when it comes to the "attacker" role. Note that, as of 9/25, the 1xMk.1 Naval Mine does almost twice as much damage to bases as the regular 1x1000 pound bomb. This quirk will come in very handy in some later bombers...
Douglas TBD-1 Devastator
Basically a Kingfisher with a better turn time (on paper, at least), more bombs, an offensive .50 instead of a .30, and no floats. The closest thing you can get to a proper level bomber at 1.0, at least in the American tree.
Douglass B-18A Bolo
The B-18A is decently quick, nimble, climbs well enough, and carries a decent bomb load. It's defensive armament is lacking, but you should be able to avoid most confrontations in this little beauty. It can't one-shot bases (IIRC) but it flies well enough that you can usually evade enemies long enough to drop the second load (and many more).
Consolidated PBY-5 Catalina, -5 and -5A
Slow, with decent defensive armament, and carrying the largest bomb load thus far, the Catalina flying boats are a fine introduction to the "heavy bomber" playstyle. If you can survive long enough to reach a base, your 4x 1000lb bombs can delete the base in a single pass. Note that the Catalinas have access to a 4x Mk.1 Naval Mine load, which can delete TWO bases with a single bomb load! Not that that's necessary in arcade, since your bombs will reload between bases, but whatever. The PBY-5 and the PBY-5A are identical beyond the 5A having landing gear and the 5 being water landing-only.
Martin PBM-1 Mariner
Slightly faster, larger, and better-armed than the Catalina, the Mariner is a superior aircraft that fills the same role as the PBY-5. Note that the Mariner does NOT have access to the Mk.1 naval mine - the only major downside to using this vehicle over the Catalina.
Martin B-10B
I unfortunately have no experience with this aircraft, although I suspect that it'll play like a slower B-18A (with double RP and SL rewards, of course) based on the stat card and the fact that the B-18A was based off of this aircraft. Will update if I end up purchasing and playing with this plane.
